The types of plastic seen in the bottle and the bowl are thermoplastic and thermosetting plastic.
- The plastic bottle is made of thermoplastic. These types of plastics have a low melting point and low tensile strength. They can be remoulded to various types of shapes. They get hard on heating and cool down quickly. That's why it got reformed by putting hot water on it.
- On the other hand, the plastic bowl is made of thermosetting plastic. These plastics have a high melting point and high tensile strength. They don't get heated easily and are difficult to deform. That is why when hot water is poured over the bowl it doesn't get reformed.
